Child-proof closure device

Abstract

The present invention relates to a child-proof closure for a container containing a dangerous substance comprising a body adapted to be fitted over a container with a top portion and a continuous side wall depending downwardly from the top portion. The closure comprises a series of interlocking elements on the top portion and the side wall that move in a predetermined sequence to facilitate access to the substance. The interlocking elements are slides adapted to slide within corresponding grooves. The closure further comprises a membrane underneath the top portion comprising an opening provided for limited distribution of the substance. The opening is accessible only after the interlocking elements are in the open position. The closure comprises two vertical slides that interlock opposite sides of a horizontal slide. The horizontal slide moves left and right and the vertical slides move down. The horizontal slide controls access to the container's contents
